Do opportunistic snap elections affect political trust? Evidence from a natural experiment

Abstract

Snap elections, those triggered by incumbents in advance of their original date in the electoral calendar, are a common feature of parliamentary democracies. In this paper, I ask: do snap elections influence citizens’ trust in the government? Theoretically, I argue that providing citizens with an additional means of endorsing or rejecting the incumbent – giving voters a chance to ‘have their say’ – can be interpreted by citizens as normatively desirable and demonstrative of the incumbent's desire to legitimise their agenda by (re)-invigorating their political mandate. Leveraging the quasi-experimental setting provided by the coincidental timing of the UK Prime Minister, Theresa May's, shock announcement of early elections in April 2017 with the fieldwork for the Eurobarometer survey, I demonstrate that the announcement of snap elections had a sizeable and significant positive effect on political trust. This trust-inducing effect is at odds with the observed electoral consequences of the 2017 snap elections. Whilst incumbent-triggered elections can facilitate net gains for the sitting government, May's 2017 gamble cost the Conservative Party their majority. Snap elections did increase political trust. These trust-inducing effects were not observed symmetrically for all citizens. Whilst Eurosceptics and voters on the right of the ideological spectrum – those most inclined to support the incumbent May-led Conservative government in 2017 – became more trusting, no such changes in trust were observed amongst left-wing or non-Eurosceptic respondents. This study advances the understanding of a relatively understudied yet not uncommon political phenomenon, providing causal evidence that snap elections have implications for political trust.
